Robin's Egg Nebula

NGC 1360, also known as the Robin's Egg Nebula, is a planetary nebula in the constellation of Fornax. It was identified as a planetary nebula due to its strong radiation in the OIII bands. Reddish matter, believed to have been ejected from the original star before its final collapse, is visible in images.

Planetary nebulae can take a wide variety of shapes. Most show a distinctive and well marked symmetry, which can vary from more or less spherical, to a doughnut-like annulus or to bi-polar, butterfly-like objects. Planetary nebulae also usually have well-defined boundaries, sometimes even a shell-like structure. For reasons that are not understood, NGC 1360 in Fornax defies all these conventions, yet its colour still clearly identifies it as a planetary nebula. The green hue is oxygen, excited by the hot central star, and to the north-east of the nebula is a faint red smudge, probably traces of material ejected before the star became a true planetary nebula.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
